Bug#852513: system unbootable on Lenovo x260 / efibootmgr ENOSPC

[Harald Welte]

I can confirm a similar (probably identical) issue on a Lenvoo x260 with
grub 2.02~beta3-4 and beta3-5, but not with <= beta3-3.

Please see #852748 for all related information.

Removing files form /sys/fs/pstore/ and even deleting other
entries with efibootmgr manually didn't solve the issue.  At this point,
downgrading to grub2 2.02~beta3-3 or earlier is the only known
workaround.
